Jiangshanosaurus was a titanosaurian sauropod that lived approximately 105 million years ago, during the Albian stage of the Early Cretaceous. Its remains were discovered in the Jinhua Formation of Lixian Village, Jiangshan county, in the eastern Chinese province of Zhejiang. The type and only known species, Jiangshanosaurus lixianensis, was formally described by Tang Feng and others in 2001. Known material of J. lixianensis includes elements of the shoulder, back, pelvis, femur and tail. Although Jiangshanosaurus initially defied precise placement within Titanosaura, a recent paper considers it to be outside Lithostrotia.
